The structural height is 291.6m and the building height is 304.1 m. Two structural systems of RC frame-core wall and hybrid frame-core wall are compared technically and economically. Results show that hybrid frame-core wall structural system costs more of 351 yuan/m2(accounting for only 16.7% of the total cost of the structure) and can increase effective use area of 21.0m2 on ground floor (accounting for 1.05% of the construction area). Moreover, the hybrid frame-core wall structural system can save construction duration of five months. Overall, the hybrid frame-core wall structural system has comparative advantage.Keywords: RC frame-core wall; hybrid frame-core wall; steel reinforced concrete column; technical economic and comparison作者简介：刘晓春，高级工程师，Email：Lxc_727@163.com。参考文献［1］徐培福，傅学怡，王翠坤，等. 复杂高层建筑结构设计［M］.北京：中国建筑工业出版社，2005.［2］唐增洪，刘晓春，胡鸣,等. 无锡茂业城主塔楼超限高层结构设计［J］.建筑结构，2013,43（22）：49-52,60.
